Replacing a Toilet Drain Pipe: Mistakes to Avoid Replacing a Toilet Drain Pipe: Mistakes to Avoid

Plumbing is no easy challenge, especially when it comes to replacing a toilet drain pipe. Very often the problem with toilet drain pipes is that there is no adequate ventilation that leads to the piping system. The drains will not work if no proper ventilation is available. However in some cases removal and replacement of a section of an old nonfunctional or damaged pipe might be necessary.

Never Leave the Water Supply On

Before even embarking on this project, make it a point to turn off the water supply. Flushing of the tank will naturally cause flushing of the water in the basin of the toilet too! To prevent mishaps whilst replacing your toilet drain pipe, never leave the water supply on. To turn off the water supply turn the emergency shut off which can be found right beside the toilet tank.

Don’t Saw the Drain Pipe with the Wrong Tool

When sawing a PVC pipe never use a normal saw or sharp object. The ideal tool to use is a skill saw. This will not leave any rough edges on either side of the pipe which has just been cut. Once you have cut the PVC pipe, clean the burrs and edges left by the saw and assemble the old pipe with the new one. Remember that the straighter the pipe has been cut the better it would be to attach the two ends of different pipes together.

Attach Pipes Properly

When gluing PVC pipes together the first thing you should do is to add primer to the end of one pipe as well as to the end of the other pipe. It is important to let the primer dry before applying clear PVC cement. This also applies when attaching a pipe to a hub. A hub is the curved part of the piping system which connects one straight pipe to another.

Don’t Use the Toilet Immediately!

Once you have replaced the piping system give time for the gluing effect to take place. During this period of time the toilet should not be used or water should not be flushed through it. Estimated time needed to wait before using your toilet depends on the room temperature since in higher temperatures clear PVC cement takes longer to solidify.

Don’t Use PVC and Glue without Proper Ventilation

PVC and glue can be toxic and harmful to your body if you are not working in a ventilated environment. Closed shafts or rooms are not always properly ventilated. Some studies have shown that glue and PVC in high doses and in the absence of adequate ventilation can result in neurological impairment. If the room cannot be ventilated properly take regular breaks as frequently as possible whilst doing this task.

Use Multi-Purpose Cement At Your Own Risk

Multi-purpose cement can be used for PVC, CPVC and ABS. However the downside is that multi-purpose cement may not be code approved for drain line use. To avoid starting all over from the beginning, if you have a PVC piping system (which is the most common nowadays), use clear PVC cement.

As indicated by these tips, replacing a drain pipe is no easy task. Lots of precautionary measures must be taken as you can easily go wrong. If you do not take necessary precautions you might face the daunting prospect of starting this tedious task all over again! So for efficiency’s sake it is best to be careful from the first time round!
